  1. Classification of Living Things • Chapter 8 Section 2

  2. Who developed the scientific naming system? • Carolus Linnaeus

  3. What is binomial nomenclature? • A two word naming system used to name organisms • Example- Panthera leo

  4. What language is used for binomial nomenclature? • Latin

  5. First word of scientific name • Genus • Represents a group of similar species • Always written with a capital letter and italicized when possible • Example- Panthera

  6. Second word of scientific name • Species • Represents a feature of an organism, identifies a place, or honors a person • Written in lower case and italicized when possible • Example- leo in the scientific name Panthera leo • Can mate and produce fertile offspring

  7. Why are scientific names used? • Four reasons • Avoid mistakes- many organisms have more than one common name • Organisms with similar evolutionary histories are classified together • Scientific names give descriptive information about a species • Information about organisms are organized easily and efficiently

  8. What characteristics do today’s scientists use to help them classify? • Similarities in structure • Fossils • Hereditary information • Early stages of development

  9. What is Phylogeny? • Evolutionary information about an organism (how it has changed over time)

  10. what are the 7 levels of classification? • Kingdom • Six different ones- Animals, Plants, Fungi, Archaebacteria, Eubacteria, and Protists • Phylum • Class • Order • Family • Genus • Species • The more levels that are shared, the more closely related organisms are

  11. Examples of Classification levels

  12. MOre Examples

  13. Which ones are more closely related?

  14. Classification Rap

  15. NAME AND DESCRIBE TWO TOOLS FOR IDENTIFYING ORGANISMS • Field Guides- contains descriptions and pictures of organisms and information about where they live • Dichotomous Keys- a list of paired statements that identify characteristics of organisms; unique to type of organism being identified

  16. Create a dichotomous key Step 1 a. Vehicle is red Go to step 2 b. Vehicle is not red Go to step 3 Step 2 a. Vehicle has a stripe Camaro b. Vehicle has no stripe Mustang Step 3 a. Vehicle is yellow Corvette b. Vehicle is not yellow Go to step 4 Step 4 a. Vehicle is an SUV Acadia b. Vehicle is not an SUV Sonata

  17. More dichotomous key practice Step 1 a. Shoe is a hightop Go to step 2 b. Shoe is not a hightop Go to step 3 Step 2 a. Shoe has a star on it Converse b. Shoe does not have a star on it Nike Step 3 a. Shoe is mostly black Nike b. Shoe is not mostly black Go to step 4 Step 4 a. Shoe is mostly white Reebok b. Shoe is mostly red Puma
